rlhis downward movement of the arm 58 f alsolmoves the coin slot locking and counting Vmechanism operating member 55 into the position, shown in Figuren and moves the benty end 5710i? the arm 56 through the slot 47 and into the coin slot 17, thereby locking the coin slot against the entrance ot a coin, While the person is in the'room.

"lhe person in leaving the room opens the door by turning the handle 3l on the inside `of the door, to the lett. rlhis turning of the .handlel partly rotates the bolt plateV 30 and brings the arm 341: on thepbolt plate 30 to the lett andagainst the shoulder` 35 on the bolt 22 and moves the bolt 22 inwards, freeing the bolt from the striker and unlockingthe door.

ln this opening ot the door by the inside lhandle 3l, the stud 32 Von the bolt plate 3 0, engages with the curved arm 59 ofthe coin slot locking and counting mechanism operating member and moves this member 55-l back` into its normal position, as shown inA Figure 8, therebymoving the coin slot loclf ingenti 57 out of ther/coin slotl?.
